Specification of Letters Patent.

Patented Alle'. 29, 1911.

Application filed December 21, 1910. Serial No. 598,561.

To all whom it may concern:

Be it known that I, HENRY A. Bonos, a citizen of the United States, and a resident of Manchester, in the county of IIartford and State of Connecticut, have invented certain new and useful Improvements in Transmission-Gearing, of which the following is a specification.

The object of the invention is to produce a simple and effective transmission gearing for use in transmitting motion from a driving to a driven shaft either in the same or opposite directions.

The embodiment of the invention illustrated in the drawings is designed particularly for use as a transmission gear for power driven vehicles, such as boats, automobiles, etc.

Referring to the drawingsmFigure 1 is a view of my transmission gear in side elevation. Fig. 2 is a central vertical section thereof. Fig. 3 is a transverse section on the line 8, 3, of Fig. 2. Fig. l is a longitudinal section on the line 4, 1, of Fig. 3.

Referring to the drawings a denotes the frame in which the gearing is supported, this frame being provided with lateral projections o at each end, by means of which it may be secured in place on suitable girders or blocks. rlhe frame has bearings c, c at each end.

l denotes the driving shaft which may receive its power direct from the motor, and 10 the driven shaft to which the propeller blades are secured.

11, 12 are friction cups having hubs 11a, 1,2, located in the bearings c, of the frame. The hub of the friction cup 11 is .located free to turn in the bearing c. The

hub of the friction cup 12 is located in the bearing o and keyed thereto. The driving shaft 1 passes through the hub of the frietion cup 11 and is keyed thereto as at 2. The driven shaft 10 passes through and rotates v in lthe hub 12L of the friction cup l2.

stood by reference to Figs. 3 and t where it is more clearly illustrated.

50 denotes the gear on the driving shaft which meshes with the gears 1, a2,whieh are supported in suitable bearings in the casing. llast on the shaft with the gears 5l, 52, or formed integrally with them, are gears 53, 5d, which are in mesh with gears 55, 5G, also located in suitable bearings in the casing, these gears 55, 56, in turn meshing with the gear 57 on the driven shaft l0.

When the shifting sleeve is in its middle or neutral position as indicated in Figs. 1 and 2, both of the clutch rings are contracted so that the gear casing` is quite disconnected from either one of the :friction cups. The resistance which the water presents to the propeller blades prevents the driven shaft from rotating and in consequence the gear casing rotates with the driving shaft 1 but at about two-thirds of its speed. I'Vhen the shifting sleeve is moved to forward position causing the clutch ring 21 to engage the friction cup ll the gear casing is caused to travel `at the same rate of Speed as the driving shaft l; all gears are thus locked and the driven shaft rotates in the saine direction and at the same speed of rotation as the driving shaft 1. If now the shifting sleeve is thrown to its rearward position engaging the clutch ring 22 with the friction cup '12 it will be seen that the casing is prevented from rotation owing to the fact that the friction cup l2 is keyed in the bearing c of the frame a. In consequence the driven shaft 210 is rotated in an opposite direction and at about twothirds the speed of the rotation of the drivingl shaft.

This structure provides a very simple and extremely ellicient transmission gearing; one which is able to transmit a large amount of power in comparison to its size, and a gearing which runs very quietly either in forward or reverse speeds.

A simple enllnuliment of the invention is illustrated. I am aware that additions may be made to the striwture and that it is Susceptiblc to minor lnmlitications without departing from the spirit of the in\\'ention.

I claim A transmission gearing comprising a frame having alined bearings, a friction cup rotatably mounted in one of said bearings, and a second friction cup fixcdly mounted in the other bearing, a gear casing located between Said friction oups, clutch members at each end of said Casing adapted for ooperation With said oups, a driving shaft passing through and keyed to said rotatable eup and extending into the interior of said Casing, a driven shaft passing through and rotatable in said fixed Cup and extending into the interior of said casing, gears secured to the abutting ends of said shafts, intermediate gears mounted in said casing and frame, forming a driving Connection between the gears at the ends of said shafts, a Shifting sleeve mounted exteriorly of the Casing and overi5 lying the ends of Said friction cups and adapted for longitudinal movement, and means carried by said sleeve and adapted to operate said clutch members one at a time.
